Biofuel production from renewable sources is generally considered to be one of the most sustainable alternatives to fossil fuels, and a viable means of sustainability for the environment and the economy. Because of their rapid growth rate, CO2 fixation ability and high lipid production efficiency, microalgae are currently being promoted as an ideal third generation biofuel feedstock; they also do not compete with food or feed crops, and can be grown on non-arable soil. Biofuels can be generated in combination with flue gas CO2 mitigation, wastewater treatment and high value production. Seawater can be used to achieve microalgal farming employing microalgal organisms as the source. To be a realistic option, a biofuel must have few features such as net energy gain, eco-friendly, economically efficient and implementable in large volumes without affecting resources demand. In this study we present an overview of the use of microalgae for the production of biodiesel, including its cultivation, harvesting, and processing. Further it is suggested that biodiesel is an effective renewable substitute for petroleum diesel.
